To all whom t may concern: l l

Beit known that I, PETE -DUNFoRD, a citizen of the United States, residing at-Summit,

\ in the county of Emanuel andState of Georgia, have invented a new and useful Cotton- Press, of which the following is a specification. y

This invention relates to pressers for'forming material into bales, and while capableof general application is designed more. especially for the formation of cotton bales.-

One object of the invention is to provide a novel form of press-box inV conjunctionvv with a pair o f oppositely-movable plungers, one of whichmoves to effect initial compression of the material in the baling-chamber and then becomes locked to form a head-block for resisting the movement of the material during the operation of the second or main com.- pression-plun er.

A further o ject of the invention is to provide means for readily controlling the operation of the plunger and to so arrange the gearing connections of the same vthat during the compressin operation the movement will be slow an powerful yand inreturning to normal position the 'movement will be rapid, so that the parts may be quickly adjusted to initial position in readiness to permit the introduction of the material to form another bale.

A still further. object of the invention is to provide improved means for discharging the bale after t e completion of the operation.

With these and other objects in view, as will more fully hereinafter appear, the -inventionconsists in certain novel features of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, andparticularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advanta es of the invention. v

the accompanying drawings, Figure 1 is a verticall section of a baling-press constructed in accordance with the invention.- Fig. 2 is a plan view of the same parts being broken away in order to more clearly illustratel the construction. Fig. 3 is a sectional plan view of the press on the line 3 3 of Fi 1. Fig. 4 is a similar view on the line 4 4 oFig. 1.

12 and near the bottom by beams 13, while auxiliary transverse beams 1 4 are arranged some distance'below the top of the frame.

The baling-chamber is formed in sectionsf andthe bottom of said chamber comprises a throughout the several figures of the drawat the opposite ends of the press at a point 65` i plunger 15, which is moved from the full-line position shown in 1 to the dotted-line position shown in the same figure during the final compressing operation. The side walls' 16 of the ovver portion of the baling-chamber are rigidly connected tothe frame and the vside walls 17 ofthe upper portion ofsaid chamber are also rigidly secured to said frame. L

At the top of the chamber are arranged inchned hopper members 18 to facilitate the introduction of the material to be compressed. The intermediate portion of the baling-chamber' is formedof two side and two end walls, all of which are of the same construction and each` ofwhich may be removed independent of the others. Each lof these Walls 2O comprises a pair of horizontally-disposed parallel bars 21,A the end portions of which are reduced in thickness and bear against the inner faces of the vertical posts 1 1, said posts being preferably rounded at thepoints where theyl engage with the bars 21. These bars are connected by metal plates 22, which are rigidly bolted to the bars and are spaced from each other, as s hown in Figs. 1 and 4, to permit the introduction of the bands or ties which are placed around the bale to hold the same compressed. The reduced endl portions of the bars 21 are so arranged that if one of the side members of the press-box is moved endwise its bars may be removed from engagement with the vertical posts at one endand then by movement in plish the desiredresult. To the central por-x tion of the plunger is secured a double rackbar 26, the upper end of which is secu-red to a frame 2,7, and the frame, which preferably is in the form', offdiagonally-disposed bracing IOO TIO

` usual manner.

members, is rigidly secured to the corners ofV the plunger in order to form a rigid structure and prevent yielding of any part of the plunger during the compression operation.

The upper frame 12 is provided with bearings for the support of a pair of parallel shafts 29 and 30, carrying gears 29 and 30, that intermesh with rack 26. The shafts also carry friction-wheels 31 and 32, respectively, these Wheels being of different diameter and being alternately engaged by a frictionwheel 33, the larger wheel 32 being driven during the compression-stroke of the plunger and the smaller wheel 31 being driven during the return of the plunger to its initial position.

The friction-wheel 33 is mounted on a shaft 34, the outer portion of which is held in a pivotally-mounted bearing 35, and on the outer end of the shaft are fast and loose pulleys 37 38, a suitable belt and belt-shifting mechanism being employed and connected in the rlhe inner portion of the shaft 33 passes through a bearing formed in a slidably-mounted block 39, to which is secured a slide-bar 40, and the outer end of the bar is connected to an operating-lever 41, which may be locked in any suitable position by a notched rack 42 and a latch or other locking device carried by the lever. When moved to one position, the shaft 34 will be slightly shifted to permit the friction-wheel 33 to engage the friction-wheel 32, and if moved to the opposite position the friction- Wheel 33 will be engaged with the frictionwheel 31.

At the opposite ends of the plunger 25 are arranged spring-pressed bolts 42, that preferabiy are provided with inclined end portions, so that when the plunger is depressed past the transverse beams 14 the spring-bolts will be driven inward and will then be thrust outward to the position shown by dotted lines in Fig. 1, thus automatically locking the upper plunger from upward movement, and said upper plunger thus forms a fixed headblock during the remainder of the compressing operation. The upper plunger is provided with bearings for the reception of a transversely-disposed shaft 44, that is connected to the several bolts 42 and is provided with an operating-lever 45 to withdraw all of the bolts simultaneously and permit the upward movement of the head-block after the formation of each bale.

The lower bracing-frame 13 is provided with bearings for the support of a pair of shafts and 51, that carry friction-wheels 52 and 53, respectively, and with these may engage a friction-wheel 54, carried by a shaft 55. The shafts 50 and 51 are further provided with intermeshing gears 56 of uniform diameter, and said gears intermesh with vertical racks 57, formed on a U-shaped frame 58, that is adapted to suitable guideways 59, and at its upper end is connected to the lower plunger 15. The outer portion of the shaft extends through a bearing-block 60, and the inner portion of said shaft is carried by a slidably-mounted bearing 62, that is carried by a bar 63, extending through suitable guiding-openings and provided at its outer end with a handle 64, which when moved in one direction or the other will shift the position of the shaft and cause the friction-wheel 54 to engage either the friction-wheel 52 or the friction wheel 53. The bar is held from movement bya pair of pawls 65, that are pivoted to the bar and engage with the teeth of a double rack 66, secured to the bed-plate of the machine or to the iioor adjacent to thel machine.

The friction-wheel 53 is of much less diameter than the friction-wheel 52 and is engaged by the friction-wheel 54 when the plunger is to be lowered after the formation of a bale. During the formation of a bale the frictionwheel 54 is kept in engagement with the friction-wheel 52, so that a slower and more powerful movement is secured. The outer end of shaft 55 carries fast and loose pulleys 67 and 68, to which a suitable belt is applied.

In theJoperation of the device the parts are normally in the position shown in Fig. 1, and the material to be compressed is fed. from the gin into the baling-chamber. After the baling-chamber is pai tly 'filled with loose cotton the lever 41 is operated for the purpose of engaging the friction-wheel 33 with the friction-wheel 32, and the plunger is driven down part of the way, slightly compressing the cotton, and may then be raised in order to permit the introduction of a fresh. quantity, and this operation may be repeated a number of times until at the final movement of the upper plunger 25 said plunger is forced down until the bolts 42 engage under the transverse bars 14 and the plunger is then. rigidlylocked in place and forms aiixed headblock. The handle 64 is then manipulated to throw the friction-wheel 54 into engagement with the friction-wheel 52, and the lower plunger 15 is forced up in order to effect the iinal compression of the bale, after which the tying may be accomplished in the usual manner. The side walls 20 or any number of them may be removed, and after the upper plunger is retracted the lower plunger serves as a support for the bale, and the latter may be slid out from the side or from the end of the baling-chamber, after which the side walls are replaced and the lower plunger is lowered in readiness for a second operation.

Having thus described the invention, what is claimed is- 1. In a baling-press, a press-box having detachable side walls each formed of a plu- .rality of spaced bars, and spaced plates extending across and securing the bars together, the bars being removably held in place by the frame of the press.
